1. Daisy Wheel

There is a round wheel that looks like a flower, and it has many small petals. Each petal has a letter or symbol. The wheel spins to bring the right letter in front of the hammer. When the hammer hits it, the letter prints on paper. This wheel is the main part that gives the printer its name.

2. Print Hammer

There is a small hammer that strikes the petals of the daisy wheel. It presses the ink ribbon against the paper to print a letter. The hammer works fast and prints one character at a time. It controls how strong and clear the print looks. This part makes every letter appear neat and sharp.

3. Ribbon Cartridge

There is a ribbon cartridge that holds the ink ribbon safely. It gives color to the printed letters. When the hammer hits the ribbon, ink moves to the paper. The cartridge is easy to replace and keeps the printer ready for work. It helps in keeping prints dark and clean.

4. Platen

There is a round roller behind the paper called the platen. It holds the paper tight when printing happens. The platen helps keep the paper smooth and straight. It also supports the printing pressure made by the hammer. This makes each print line look even and tidy.

5. Carriage

There is a moving part called the carriage that holds the daisy wheel and hammer. It slides from one side to the other while printing. The carriage helps letters appear one after another in a line. It moves with the help of the motor and belt. This part makes sure the printing stays straight and aligned.

6. Stepper Motor

There is a stepper motor that controls the movement of the daisy wheel and carriage. It turns in small steps to keep actions accurate. The motor helps the wheel rotate to the right letter. It also moves the carriage smoothly across the page. This part gives motion and life to the printer.

7. Drive Belt

There is a drive belt that connects the motor and the carriage. It helps the carriage move from side to side. The belt keeps the motion smooth and balanced. When the motor turns, the belt pulls the carriage in the right direction. It is a small but important moving part.

8. Paper Feed Mechanism

There is a paper feed system that moves the paper upward after each line. It makes sure that the paper stays in the right place. The feed works gently to avoid paper jams. It helps print each line clearly without overlap. This part makes printing easy and steady.

How the Parts Work Together

There are many parts of Daisy Wheel Printer, and they all work together like a small team. Each part has a special role that helps the printer make neat and clear letters on paper. When one part moves, the next part follows it. The full process is simple but smart, and it shows how well this old printer design worked.

Here is how the parts of Daisy Wheel Printer work together step by step

1. Control Board Receives Data

There is a control board that reads the printing data sent from the computer. It gives orders to all other parts such as the motor, carriage, and hammer. The board sends small signals that guide each step of the printing process. It works like the brain that keeps every part doing its job at the right time.

2. Stepper Motor Starts Moving

There is a stepper motor that begins to turn slowly in small steps. It rotates the daisy wheel until the right petal with the correct letter reaches the printing point. The motor also moves the carriage along the page. It keeps all movements steady and smooth for perfect printing.

3. Daisy Wheel Turns to the Right Letter

There is a daisy wheel that spins based on the signal from the control board. When it stops at the right character, the printer gets ready to print. Each petal on the wheel holds one letter or symbol. The wheel movement is controlled carefully so that the print stays accurate.

4. Print Hammer Hits the Petal

There is a hammer that quickly strikes the petal on the daisy wheel. The hammer presses the ink ribbon and paper together. This hit creates a letter on the paper surface. The hammer moves very fast and repeats this action for every new letter that needs printing.

5. Ribbon and Ribbon Advance Work Together

There is a ribbon cartridge that carries the ink ribbon. When the hammer hits, the ribbon leaves a mark on the paper. Then the ribbon advance mechanism moves the ribbon forward a little. This step keeps printing dark and clear because it uses a fresh part of the ribbon each time.

6. Platen and Paper Feed Move the Paper

There is a platen roller that holds the paper tight during printing. After one line is complete, the paper feed mechanism moves the paper upward. The paper moves in small steps to keep every line even. The tractor feed or paper guide helps in moving the paper smoothly without slipping.

7. Carriage Slides Across the Page

There is a carriage that carries the daisy wheel, hammer, and ribbon. It slides from left to right while printing each line. The drive belt and stepper motor control its motion. The carriage return mechanism then brings it back to the start for the next line. This helps in keeping the text in a straight line.

8. Sensors Keep Track of Motion

There are sensors inside the printer that keep checking the position of the carriage and paper. They tell the control board if everything is in the right place. The microswitch assembly also helps by detecting when the carriage reaches its end point. These small parts make sure printing stays accurate.

9. Power Supply Keeps the Printer Active

There is a power supply that gives energy to all the parts. It powers the motor, control board, sensors, and hammer. Without it, the printer cannot move or print. The power system works quietly but keeps every part ready and active.

10. Housing Keeps Everything Safe

There is a strong housing that covers all parts of the printer. It protects them from dust and outside damage. The housing also keeps vibrations low during printing. It helps all moving parts stay in place and work properly together.
